What is the Arithmetic mean of the first 'n' natural numbers?
Answer & Solution
Correct Answer:
Option
B
Sum of first $$n$$ natural numbers $$\frac{{n\left( {n + 1} \right)}}{2}$$
∴ Required average $$ = \frac{{n\left( {n + 1} \right)}}{{2 \times n}} = \frac{{n + 1}}{2}$$
∴ Required average $$ = \frac{{n\left( {n + 1} \right)}}{{2 \times n}} = \frac{{n + 1}}{2}$$
